Theoretical Helioseismology and Asteroseismology

首席调查员(PI)建议使用太阳和恒星振荡数据来了解太阳和恒星的内部。这种研究太阳和恒星的技术相对较新，分别被称为日震学和星震学。特别是，PI提出：1.对太阳辐射内部可能存在的极向磁场和环向磁场施加限制；2.从现象学的角度推断太阳发电机磁场对振荡数据和作为经度函数的全球表面温度差的影响；3.确定某些AP恒星中的磁场以及这些恒星脉动的原因和方式。建议与密歇根州立大学的库恩、波兰的DziemBowski、Kozlowski和Sienkiewicz、日本的Shibahashi和南非的Kurtz合作。

The Principal Investigator (PI) proposes to use solar and stellar oscillation data to learn about the interiors of the sun and the stars. This technique of studying the sun and the stars is relatively new, called helioseismology and asterseismology, respectively. In particular, the PI proposes 1. to place limits on possible poloidal and toroidal magnetic fields in the Sun's radiative interior, 2. to deduce phenomenologically the effect of the Sun's dynamo field on the oscillation data and on the global, surface tempeture dips as functions of longitude, and 3. to determine the magnetic fileds in certain Ap stars and why and how these stars pulsate. Collaborations are proposed with Kuhn of the Michigan State University, with Dziembowski, Kozlowski, and Sienkiewicz of Poland, with Shibahashi of Japan, and with Kurtz of South Africa.
